摘　　要：移动自组织网络在专用通信领域中得到广泛重视,如何提高其媒体接入效率是研究的热点。文中针对移动自组织网络中多节点共享资源时媒体接入的频谱利用率和接入效率问题,基于多用户检测理论设计和实现了多节点共享物理资源的媒体接入协议,与传统CSMA/CA协议相比,提高了节点并发传输数量,频谱效率改善可达4.28倍。Mobile ad-hoc network is widely used in private communication. How to improve the ultization efficiency is a current hot research. The article focuses on mobile media access problems of mobile ad-hoc network when multi-node shares resources based on multiuser detection. The efficiency of spectrum reuse is improved through the design and implementation of MAC protocol of mobile ad-hoc network based on multiuser detection. Compared with the traditional CSMA/CA protocol, the spectral efficiency is improved up to 4.28 times.

关 键 词：移动自组织网络 多用户检测 媒体接入协议
